“…However, a great deal of research is still needed to establish an industrial-scale culturing system (Fayaz Bhat and Fayaz 2011). Other alternative protein sources investigated both as food and feed are as follows: seaweed (Mohamed et al 2012;Makkar et al 2016), duckweed (Appenroth et al 2017), canola/rapeseed , micro-algae and other microbes (Vigani et al 2015), and insects (Van Huis et al 2013). The latter option is the primary focus of this review.…”

With a growing world population, increasingly demanding consumers, and a limited amount of agricultural land, there is an urgent need to find alternatives to conventional meat products. Livestock production is, moreover, a leading cause of anthropogenic-induced climate change. To mediate this, more sustainable diets are needed, with reduced meat consumption or the use of alternative protein sources. Insects are promoted as human food and animal feed worldwide. In tropical countries, edible insects are harvested from nature, but overexploitation, habitat changes, and environmental contamination threaten this food resource. Therefore, sustainable harvesting practices need to be developed and implemented. We provide examples of (1) aquatic insects whose populations are threatened by pollution, (2) caterpillar species in Africa that are disappearing due to overexploitation and habitat change, (3) edible insects species that are considered pests in agro-ecosystems, and (4) edible insect species that can be conserved and enhanced in forest management systems. Insect farming can be conducted either on small-scale farms or in large-scale industrialized rearing facilities. We review the environmental sustainability of insect farming compared to livestock production. The major environmental advantages of insect farming compared to livestock production are as follows: (1) less land and water is required; (2) greenhouse gas emissions are lower; (3) insects have high feed conversion efficiencies; (4) insects can transform low-value organic by-products into highquality food or feed; and (5) certain insect species can be used as animal feed or aqua feed. For instance, they can replace fish meal, which is becoming increasingly scarce and expensive.However, edible insect species intended for production should be screened for risks to humans, animals, plants, and biodiversity.

“…The medical potential of natural products is a focus of attention as they are inexpensive to produce and have relatively fewer side effects compared to drugs (Lee et al 2010;Mohamed et al 2012). Macroalgae are prolific sources for numerous natural compounds with promising potential for both prevention (Lee et al 2013) and treatment of several diseases including cancer (Hiroishi et al 2001;RademakerLakhai et al 2005) and diabetes (Nwosu et al 2011).…”

Macroalgae of Izmir Gulf: Dictyotaceae exhibit high in vitro anti-cancer activity independent from their antioxidant capabilities

2016

In this study, 24 marine macroalgae collected from the coastline of Izmir Gulf were examined for their antioxidant activities and their effects on cell proliferation. Crude extracts were obtained from samples with cold methanol extraction. Antioxidant activity was evaluated as 2,2-diphenyl-1-picryl-hydrazyl (DPPH) radical scavenging activity and total phenolic content (TPC); growth inhibitory effects of the extracts were determined by using WST-8. Amongst the species, Polysiphonia denuata (Rhodophyta) and Cystoseira species (Phaeophyceae) have been noticed by their high DPPH radical scavenging activities and TPCs. As expected, there was a strong correlation between these tests. Dictyota dichotoma (Phaeophyceae) showed the highest anti-cancer activity on MCF-7 cells with an IC 50 of 17.2 ng mL -1 . Flow cytometry analyses demonstrated that D. dichotoma methanolic extract strongly induced apoptosis.This extract exhibited moderate viability inhibition on MCF10A cells (IC 50 : 49.3 ng mL -1 ), suggesting a potential use of the extracts or its compounds for cancer therapy. There was no correlation between anticancer potential and antioxidant content of the extracts.

“…Recently, macroalgae have been used as a novel food with potential nutritional benefits in food industry as a valuable ingredient in any dish (soups, rice, pasta, pâté, appetisers, biscuits, etc. ) and medicine, since current research on mammals, trials on humans, and epidemiological studies have revealed their potential as a rich source of natural bioactive compounds with antiviral, antifungal, antibacterial, antioxidant, anti-inflammatory, hypolipidemic, and antineoplasteic properties (Mohamed, Hashim, & Rahman, 2012;Shalaby, 2011). Thus, there is a growing interest in research into bioactive compounds in different algae species and a lack of reports, especially on changes in the content of their bioactive compounds after culinary treatments.…”
